Title (EN) KINETIC TURBOPUMP WITH SPEED-VARYING DEVICE FOR A CLOSED CIRCUIT, PARTICULARLY OF THE RANKINE CYCLE TYPE, NOTABLY FOR A MOTOR VEHICLE
(FR) TURBOPOMPE CINETIQUE AVEC UN DISPOSITIF DE VARIATION DE VITESSE POUR UN CIRCUIT FERME, EN PARTICULIER DE TYPE A CYCLE DE RANKINE, NOTAMMENT POUR UN VEHICULE AUTOMOBILE
Abstract:
(EN) The present invention relates to a turbopump comprising a fixed casing (12, 12'; 112) comprising a pump (16, 116) with a pump rotor (14, 114) borne by a pump shaft (18, 118) and a turbine (22, 122) housing a turbine rotor (20, 120) borne by a turbine shaft (24, 124). According to the invention, the pump shaft (18, 118) is separate from the turbine shaft (24, 124) and the turbopump comprises a speed-varying device (26, 126) for generating a difference in rotational speed between the pump shaft (118, 118) and the turbine shaft (24, 124).
(FR) La présente invention concerne un turbopompe comprenant un boîtier fixe (12, 12'; 112) comportant une pompe (16, 116) avec un rotor de pompe (14, 114) porté par un arbre de pompe (18, 118) et une turbine (22, 122) logeant un rotor de turbine (20, 120) porté par un arbre de turbine (24, 124). Selon l'invention, l'arbre de pompe (18, 118) est séparé de l'arbre de turbine (24, 124) et la turbopompe comporte un dispositif de variation de vitesse (26, 126) pour générer une différence de vitesse de rotation entre l'arbre de pompe (18, 118) et l'arbre de turbine (24, 124).
